Satisfying physics sims

One capsule. Five softness levels. One glass maze.

A rose-gold capsule drops into a glass maze at 0, 25, 50, 75 and 100% soft. Some shatter it, some get stuck, one turns to liquid gold. Guess which one lands in the hole.

0 to 100% soft

Same capsule, same maze, same drop. Only the softness changes, and every step behaves differently.

  1. 0% soft: the glass maze bursting around a rigid gold capsule
    0%SOFT

    Rigid. It jams on a bend and the glass bursts.

  2. 25% soft: the capsule stuck at a bend in the glass tube
    25%SOFT

    Bends a little, then gets stuck at the hairpin.

  3. 50% soft: the capsule squeezing through the last turn
    50%SOFT

    Squeezes through every turn and drops clean in.

  4. 75% soft: the capsule landing on the marble pedestal next to the hole
    75%SOFT

    Too soft to steer. It bounces off the rim first.

  5. 100% soft: liquid gold pouring out of the glass maze
    100%SOFT

    Melts into liquid gold and pours onto the marble.

How it's made

Every frame is simulated and rendered. No AI video.

  • Our own physics

    A soft-body solver for the capsule and a particle sim for the liquid gold, written for this channel.

  • Real materials

    Thin clear glass, Carrara marble with gold inlays and polished rose gold, rendered in Blender Cycles.

  • Real sounds

    Recorded impacts and glass breaks, with silence between drops. No music.

A game is in the works

Set the softness yourself and try to land the capsule in the hole. Follow Gold & Glass to play it first.
